List of catalogs in this article: 1. How are natural diamonds formed? 2. The difference between natural diamonds and artificially cultivated diamonds. 3. How are diamonds formed? How are natural diamonds formed? 4. How to distinguish man-made diamonds from natural diamonds? 1. Diamonds are formed under the conditions of high pressure and high temperature deep in the earth. Diamond is a kind of elemental crystal composed of carbon element formed under the conditions of high pressure and high temperature deep in the earth. It is usually brought to the surface by magma through volcanic eruptions. Diamond refers to polished diamond, which is a natural mineral and the original stone of diamond. 2. Most diamonds are formed under geological high temperature and high pressure: the pressure of diamond formation conditions is 5 to 6 GPa, and the temperature is 1100 to 1500 °C. Carbon element crystallizes into graphite under high temperature and pressure, and crystallizes into precious diamond under high temperature, extremely high pressure and reducing environment. 3. Diamonds are generally formed by volcanic eruptions and brought to the surface of the earth by magma. As the magma rises, it will also capture some related minerals to the earth's surface. These will be the minerals used to find diamonds, and the more indicator minerals there are in the same soil range, the better your chances of finding diamonds. 4. Diamond processing: when processing, first use machinery for rough processing, and finally perform more delicate polishing by hand. Formation of natural diamonds: Diamonds are elemental crystals composed of carbon (C) elements formed under the conditions of high pressure and high temperature deep in the earth. The difference between natural diamonds and artificially cultivated diamonds is that the price is different: cultivated diamonds are artificially synthesized and the price is low. Cultivated diamonds are artificially simulating the formation conditions of natural diamonds, so that non-diamond-structured carbon is transformed into diamond-structured carbon, which becomes a cultivated diamond. The differences between artificially grown diamonds and natural diamonds are: different prices, different qualities, and different formation methods. The difference between cultivated diamonds and natural diamonds is as follows: the formation method, cultivated diamonds are artificially inserted into seed diamonds through technical means to form a diamond crystal structure, while natural diamonds are naturally formed, not artificially manufactured. Characteristics, a small part of cultivated diamonds can be absorbed by magnets, but natural diamonds cannot be absorbed by magnets. Mainly distinguish from three points: the formation method, cultivated diamonds are artificially inserted into seed diamonds through technical means to form diamond crystal structures, while natural diamonds are naturally formed, not artificially manufactured. Characteristics, a small part of cultivated diamonds can be absorbed by magnets, but natural diamonds cannot be absorbed by magnets. There is no difference in value between lab-grown diamonds and natural diamonds, but when you buy it, you can find that lab-grown diamonds of the same quality level are much cheaper than natural diamonds, and some are even only one-fifth of the price of natural diamonds. Different value: Although there is not much difference between cultivated diamonds and natural diamonds in appearance, it can be found when purchasing that cultivated diamonds of the same quality level are much cheaper than natural diamonds, and some are even only one-fifth of natural diamonds price. How are diamonds formed? How are natural diamonds formed? Simply put, they are the product of volcanic eruption of natural diamonds. All natural diamonds are natural diamonds formed deep in the earth's crust under high temperature and high pressure conditions, and brought to the surface by volcanic eruptions. Diamonds are formed 160-480 kilometers underground. Formation of diamonds: The earliest natural diamonds were formed in natural diamonds inside the earth, at a temperature of 900-1600°C and a pressure of (5-6)×109Pa, which is equivalent to a depth of 130-200km underground. In theory, diamonds can form at any time as long as the conditions are met. Most of the diamonds currently mined were formed 3.3 billion years ago and 1.2-1.7 billion years ago. Most diamonds are formed under geological high temperature and high pressure: the pressure of diamond formation conditions is 5 to 6 GPa, and the temperature is 1100 to 1500 °C. Carbon element crystallizes into graphite under high temperature and pressure, and crystallizes into precious diamond under high temperature, extremely high pressure and reducing environment. The exact origin of the diamond is still a mystery. Diamonds were formed hundreds of millions of years ago in high temperature and high pressure deep in the earth. It was not until more than 2400 years ago that diamonds were first discovered and mined in India. Over time, diamonds have been found in many other parts of the world. Diamond is an elemental form of carbon, pure diamond is colorless and transparent. In the natural state, pure carbon forms diamonds under high temperature and pressure, which is the so-called natural diamonds. Although diamonds are non-renewable, there are still many in nature. It is not "extremely rare" as some monopoly consortiums call it. How to distinguish man-made diamonds from natural diamonds? Observe the reflected light with a magnifying glass, and you can observe the diamond's girdle showing a very fine frosted and shiny reflection. This characteristic of diamonds is unique. 4. Look at the growth points Observed under a magnifying glass, there are often grooves and triangular growth points on the crystal surface of genuine diamonds, but these features cannot be seen in counterfeit diamonds. The characteristics of cultivated diamonds are different from those of natural diamonds. The characteristics of cultivated diamonds can be absorbed by magnets, while natural diamonds cannot be absorbed. This is also one of the differences used to identify cultivated diamonds and natural diamonds. Observe carefully, no matter what direction, natural diamonds are impossible to see through because of their reflective light, but the combination of diamonds is different, because the lower part is a mineral with a low refractive index, the reflection ability of the combination stone is poor, and sometimes light can pass through . Color The vast majority of synthetic diamonds are yellow, thirsty yellow with hourglass-shaped ribbons; while natural diamonds are colorless, light yellow and other colors. Natural diamonds are mostly colorless, and some have a light yellow color; while synthetic diamonds are mostly yellow or yellowish brown with hourglass-shaped bands. This concludes the introduction of natural diamonds and natural diamond price charts. Have you found the information you need?
